Step 2
Fully assemble the model. With a helper, lift the airplane with your index fingers to find the balance
point. The balance point (CG) should lie between the two marks on the wing. If not, try to move some
parts such as batteries to different position, or add the necessary weight to the nose or tail to obtain
the correct balance.
Preflight
As a large model, the airplane is critical of proper battery use, control linkage setups and flying
techniques. Please pay particular attention to the following areas.
Maintain the proper mechanical advantage on all control surface linkages.
Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the
correct direction and with the recommended throws). Test run the engine and make sure it transitions
smoothly from idle to full throttle and back. Also ensure the engine is tuned according to the
manufacturer's instructions, and it will run consistently and constantly at full throttle when adjusted.
Check all the control horns, servo horns, and clevises to make sure they are secure and in good
condition. Replace any items that would be considered questionable. Failure of any of these
components in flight would mean the loss of your airplane.
Never attempt to make full throttle dives!
Large models perform much more like full-size airplane than small models. If the airframe goes too
fast, such as in a high throttle dive, it may fail. The model should be flown like a full-scale airplane.
Throttle management is absolutely necessary.
Hardware checks
Double-check the setscrews in all control horns to be sure they are very tight. Periodically check
these to be sure they have not loosened over time. Always use threadlock on metal-to-metal fasteners.
Receiver Battery Selection
Be sure adequate batteries are used to power the receiver. It is recommended that a 6-volt receiver
pack is used. The pack must have a minimum of 2700mAh capacity. Use pack of 3000mAh when super
high torque servos are used.
Range check
Always range check the radio system per the manufacturer's instructions before the initial test flight
and periodically afterward.
Check the voltage of the on-board packs
ALWAYS use an ESV with a 1-amp load to check the receiver battery packs and the ignition pack
before each and every flight. If there is any doubt that the packs are questionable, DO NOT FLY
until the packs are recharged.
